Fourier描绘子在模式识别中的应用与性能分析
摘 要
本文介绍了目前最常用的Fourier描绘子，重点研究了数字图象提取轮廓时产生的量化误差和边界点不等距等因素对于Fourier描绘子系数的影响，对Fourier描绘子的几种规一化方法的特点和各自的适用范围也进行了比较，最后对Fourier描绘子识别三维空间中任意姿态的飞机在二维平面上的投影进行了实验。

Fourier Descriptors for Three-Dimensional Aircraft Recognition
() Abstract
In this paper we discuss the effect of error due to the digital representation of image such as chain code error and sampling error on the coefficient of fourier discriptor, and we compare the performance of some normalization methods. This method is applied to the three dimensional aircraft recognition.
